RUFUS A. SIMPSON, OF FERNDAL'E, CALIFORNIA.

BUTTER-MOLD To all whom it may concern:

Be it known that I, RUrUs A. SIMPSON, a citizen of the United States,residing at F erndale, in the county of Humboldt and State ofCalifornia, have invented new and useful Improvements in Butter-Molds,of which the following is a specification.

The object of the present invention is to provide a receptacle in theform of a box the sides of which can be readily spread for the purposeof discharging the contents of the receptacle. It is especially adaptedfor use as a butter mold, but can also be used to advantage forcontaining any other material which might tend to adhere to the innersurfaces of the sides of the receptacle.

In the accompanying drawing, Figure l is a perspective View of thereceptacle; Fig. 2 is a broken plan view of one end thereof; Fig. 8 is asimilar view, showing the sides and the corresponding end spread apart;Fig. 4 is a perspective view of one of the link rods; Fig. 5 is anenlarged section through a spreader.

Referring to the drawing, 1 indicates the bottom of my improvedreceptacle, to which are secured, by screws 2, the side boards 3 and theend boards 4. Said screws 2 are not screwed in so tightly as to preventsaid sides and ends being able to have a slight movement of their loweredges relatively to the screws. The ends of the end boards are receivedin vertical grooves 5 formed in the inner surfaces of the side boards,said grooves having their outer sides 6 flaring outward and the outersides of the end portions of the end boards being correspond- The effectof this construction is that, when the side boards are contracted towardeach other, the flaring sides 6 of the grooves press upon the beveledportions 7 of the end boards and press them inward. On the contrary,when the side boards are spread from each other, the end boards are freeto move outward.

Into the ends of the side boards 3, near the upper edges, and outsidethe box are screwed from the inside the threaded ends of link rods 8,and nuts 9 are screwed therein up to side boards 8, to provide properbearing surfaces thereagainst. The inner ends of said rods are formedinto loops 10, and the two loops, at each end of the receptacle,respectively surround eccentrics ll Specification of Letters Patent.

the end of the box, a cleat 15 which is used as a handle in lifting thebox.

The ends of the receptacle extend to a somewhat higher level than thesides, and, 011 one side only, opposite to, or in the same plane with,the respective ends are secured two lugs 16 which also project slightlyabove the upper edges of the sides and to substantially the same levelwith the upper edges of the ends 1, these lugs being formed with fingerpieces 17 for convenience of manipulation. The object of thisarrangement is to enable the receptacle, when used as a butter mold, andinverted, to be guided 'into the proper position, the ends of the endboards 4 and the corresponding lugs 16 forming guides which engage theedge of the bottom board and guide the butter mold into the properposition when inverted.

The apparatus is used in the following manner. The butter mold is partlyinverted and is placed so that the lugs 16 and the ends of the endboards 4 engage the edge of the bottom board. The butter mold is thenwholly inverted. The handles 13 are then turned through substantiallyone-half of a revolution. In this position the eccentrics have been soturned that the outer ends of the link rods having moved farther apart,thereby causing the side boards to spread from each other. The endboards being now released from the side boards, by reason of theinclined surfaces at the ends of said end boards being no longer c0111-pressed by the inclined or flaring sides of the grooves in the sideboards, can freely move outward, and exert no pressure upon the ends ofthe block of butter, so that the butter mold can be readily lifted fromsaid block.

I claim 1. A box, open at the top and comprising a bottom, and end andside boards secured thereto, the side boards having grooves to receivethe ends of the end boards, and means for spreading the side boards fromeach other, substantially as described.

2. A box, open at the top and comprising a bottom, and end and sideboards secured thereto, the side boards having grooves to connected withsaid side boards and having receive the ends of the end boards, flaringat their outer sides, and the outer sides of the end portions of the endboards being correspondingly inclined, substantially as described.

3. A box, open at the top and comprising a bottom, and end and sideboards secured thereto, the side boards having grooves to receive theends of the end boards, link rods loops at their inner ends, andeccentrics pivotally supported by the end boards and engaging said loopsin pairs, substantially as described.

4:. A box, open at the top and comprising a bottom, and end and sideboards secured thereto, the side boards having grooves to receive theends of the end boards, link rods connected with said side boards andhaving loops at their inner ends, eccentrics pivotally supported by theend boards and engaging said loops in pairs, levers for actuating saideccentrics, and cleats having thickened portions against which saidlevers move, substantially described.

5. A receptacle of the character described, comprising end boards, sideboards having grooves to receive the ends of the end boards, I

the end boards extending to a higher level than the side boards, and oneside board having secured thereon, opposite to the ends of the endboards, lugs rising above the edge of said side board, to form, With theend boards, guides for guiding the receptacle into position wheninverting the same, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of tWosubscribing Witnesses.
